One line? Use semicolons !
Which man tar has B?
If you want simple, with compression, something like this (might be scp, might be -C): scp2 -rpd +C /top_dir1 /top_dri2 /top_dir3 remote_host:/
A Google tells me rcp never has compression, but rsync does.
The single tar ssh stream:
- has no intermediate files, one requirement,
- ssh might work for root when rsh does not, somewhat an implicit hidden potential requirement,
- pads with nulls, a minor inefficiency cpio vs. tar (silly old command intended for tape drives),
- has no compression, so network speed will choke it considerably (ssh has +C or -C for gzp -? compression. but separate compression processes gives you choice and control and another process to pipeline larallelize the job),
- is single process, so i/o time and file search and open time will waste critical network time, not to mention single tcp socket, so there may be ack delays if max tss is not high enough, and delays if any packet is lost,
- ssh adds encrypt/decrypt overhead/delay,
- pipes and most of UNIX i/o is single buffered, so there will be time lost to blocking.
It turns out cp/*cp/rcp/scp/scp2 -r use cpio, which also has a local pass option, somewhat redundant to cp -r, but choice is good.
